COMBINED PENCIL-SHARPENER AND ERASER..

SPECIFICATION forming part of Letters Fatent No. 627,279, dated June 20,1899.

Application filed February 8, 1898. Serial No, 669,524. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH D. STAssAR'r, a citizen of the United States,residing at Portland, in the county of Multnomah and State of Oregon,have 'invented a new and useful Combined Pencil-Sharpener and Eraser, ofwhich the following is a specification.

My invention relates to lead-pencils, and

more especially to a certain improved device to be attached to alead-pencil to perform the double function of a lead-pencil eraser andpencil-Sharpener.

The object of myinvention is to provide a combined eraser and Sharpenerto be'attached to and sold with the pencil, which while being perfectlyreliable in the performance of its double function shall be so simpleand cheap asnto permit of its beingapplied to the pencil Withoutmaterially increasing its selling price.

Vith this object in view my invention consists in the improvedconstruction, arrangement, and combination of parts hereinafter fullydescribed and afterward specifically pointed out in the appended claims.

In order t0 enable others skilled in the art to which myinvention mostnearly appertains to make and use the same, I will now proceed todescribe its construction and operation, reference being had to theaccompanying drawings, forming part of this specification, in Which-Figure l is a perspective view illustrating a pencil provided with acombined eraser and Sharpener constructed in accordance with myinvention. Fig. 2 is a view, on an enlarged scale, of the upper end ofthe pencil and the attached combined eraser and Sharpener. Fig. 3 is acentral longitudinal sectional view through the same on the line 3 3 ofFig. 2. Fig. 4 is a transverse sectional view through the same on theline 4 4 of Fig." 2. Fig. 5 is a similar view on the line 5 5 of Fig. 2.Fig. 6 is a detail perspective view of the knife detached.

Like letters of reference mark the same parts wherever they occur in thevarious figures of the drawings.

Referring to the drawings by letters, A indicates the main body of apencil, upon which is securedl a tube B, provided with a series of spunthreads, asat C..

D indicates a tube having spun threads E of a size to engage the threadsO ofthe tube B, whereby the tube D may be removed or replaced bythreading it on or off at will. F is a similar tube, with spun threadsG, in which is seated a rubber eraser H.

I I indicate the iiat metal sections connecting the tubes D and F andformed integrally therewith. The tubesD and F and the intervenin g flatportions I I' were originally formed as a single straight tube havingthe threads E at one end and the threads G at the other for the samepurposes as those for which they are utilized in carrying out thisinvention. The flat intervening portions I l' are formed from `thecentral portion of the original tube by stamping by means of a die ofthe proper configuration to form these flat portions and a longitudinaltubular portion of smaller diameter than the tubes D and F and composedof a conical section .I an intervening cylindrical portion K, andaconical section L. The iiat portions I and I are thus formed of adouble thickness of metal, as shown, and the outer edge of the flatportion I is cut off, forming an opening into the space between itsthicknesses of metal.

M indicates the knife, formed of a single piece of sheet-steel bent toform the body N and blade O, as clearly shown.

A slot P is formed in the course of manufacture in the conical sectionJ, extending into the cylindrical section K. The knife M being shaped asshown is secured by placing the body N thereof between the twothicknesses of the flat section I' and securing it therein by pressure,in which position the blade O will pass through the slot P in theconical section J, exposing its edge inside said conical section, asclearly shown in Figs. 4 and 5.

To operate my invention as an eraser, it may be used in the ordinarywell-known manner, the rubber eraser H forming the outer end of thewhole structure, and to operate the invention as a pencil-Sharpener thewhole attachment is removed from the body of the pencil by turning thethreads E from the IOO threads C, reversing the pencil, inserting itspoint into the tube D and conical section J, and nally by turning thepencil in contact with the edge of the knife-blade While holding theattachment in the other end against turning until a sufficient amount ofWood has been removed and the lead properly pointed.

From the foregoing itwill be obvious that I have provided an efficientcombined pencil- Sharpener and eraser Which is so simple and cheap thatit may be sold with the pencil` themselves 'to the ordinary mechanicwould properly fall Within the limit and scope of my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by LettersPatent of the United States, is-

-1. Animproved combined pencil-Sharpener and eraser, comprisinga tube,adapted at one end to engage a tubular sleeve on the end of the penciland at the other to carry an eraser, having its intervening portionflattened at each side and formed with a smaller, tubularv section,slotted longitudinally, and a knife having its body secured to one ofthe attened portions and its blade bent over and projected through theslot, all vsubstantially as described.

2. The herein-describedimproved combined pencil-Sharpener and eraserconsisting of the tube D adapted to be attached to the pencil', the tubeF carrying the rubber eraser, the conical section J, tubular section Kthe conical section L and the fiat double-thickness laterally-projectingwings Z, l', the latter having its edge cut away, all of these partsexcept the eraser, being formed integrally, and the knife M composed ofthe body N, pressed between the two thicknesses of the section Z', and aknife-blade bent over and projected inward through the slot P in theconical section J, all substantially as set forth.

JOSEPH D. STASSART.
